Recently, Instagram has implemented a new self-expression feature. They added a "Pronouns". LinkedIn added the same field a little earlier.
More and more users feel the need to inform which gender they identify with. Transgender people in particular do this for understandable reasons. Pronouns are not obligatory and Instagram users can decide whether the pronoun will be visible to all visitors to its profile or to those who follow it.
In the UK, for example, Instagrammers can choose between his, he, him, she, her, hers, hir, e, ey, em, eir, they, them, theirs, thon, thons, per, pers, fae, faer , ze, zir, zie, xe, xem, xyr, co, cos, ve, ver, vis, vi, vir, ne, nir, nirs, nee, ner, ners, mer and mers.
Of course, we can use our own built-in profile fields, but they are not translatable and will not be displayed at the top.
